AC Expanding PU Foam (Available in 300ml & 750ml)

Efficiently seal, insulate, and fill gaps with our AC Expanding PU Foam. This versatile, self-expanding polyurethane (PU) foam is designed to provide excellent insulation and strong adhesion, making it an essential product for various construction, installation, and repair projects, particularly around air conditioning units and ducting.

When dispensed, the foam expands to fill cavities and irregular spaces, creating an airtight and watertight seal. This helps to improve energy efficiency, reduce drafts, block noise, and prevent moisture ingress. Its strong bonding properties ensure a durable and long-lasting seal.

Key Features & Benefits:

• Effective Sealing & Insulation: Expands significantly to fill gaps and voids, providing superior thermal and acoustic insulation around AC units, pipes, windows, and doors.
• Strong Adhesion: Bonds reliably to most common building materials, including concrete, masonry, wood, metal, and many plastics.
• Air & Water Barrier: Creates an effective barrier against air drafts, dust, pests, and moisture, contributing to a more comfortable and energy-efficient environment.
• Versatile Application: Ideal for installing and sealing door and window frames, filling gaps in walls, sealing pipe penetrations, insulating electrical outlets, and general construction gaps.
• Easy to Use: Applied via an aerosol can with a nozzle, ensuring controlled and efficient dispensing.

Available Sizes:

• 300ml: Convenient for smaller projects, touch-ups, and precise applications.
• 750ml: Ideal for larger projects, extensive filling, and higher yield requirements.

Our AC Expanding PU Foam is a reliable choice for achieving professional results in sealing, insulating, and filling applications.
